How much Vitamin D should I take per day?Updated a year ago

The recommended daily intake of Vitamin D depends on many factors, such as age, skin color, and level of sun exposure. The Endocrine Society recommends dosages for adults ranging from 1500 to 2000 IUs per day to maintain Vitamin D levels, although dosages up to 10000 IUs may be needed to correct a Vitamin D deficiency.[3] Approximately 29% of U.S. adults are Vitamin D deficient (<50 nmol/L).
